BOURBONNAIS, Ill. – Marquess Wilson delivered another strong performance in his bid to secure the No. 3 receiver job in the offense, with a falling-down, deep sideline catch for what would have been a 40-yard touchdown throw from Jay Cutler. Chris Williams, looked upon as primarily a returner, turned in three good catches, including a diving grab across the deep middle.

Meanwhile, rookie cornerback Kyle Fuller continues to go through his “welcome to the NFL, kid” time, being matched up against Pro Bowl wide receiver Alshon Jeffery in one-on-one drills in addition to taking Tim Jennings’ spot at left cornerback after the latter decided after one rep that his ailing quad wasn’t ready for a day of contact.

Fuller delivered a clean pass breakup against Jeffery on the first play of “team” work, and the rookie forced an incompletion on a slant route. But Jeffery got behind Fuller on a deep fade route (Fuller closed fast and the ball was overthrown) and beat Fuller with an NFL-grade push-off to make a catch across the middle.

“We have some very good receivers to compete against every day and good quarterbacks,” said defensive coordinator Mel Tucker. “So it’s a test. You can’t take a play off. It’s like sharpening steel. We should be making each other better. But definitely you have to bring your A-game when you go against our offense.”
